Emptiness formation probability and PainlevéV equation in the XY spin chain
We reconsider the problem of finding Lconsecutive down spins in the ground state of the XY chain, a quantity known as the Emptiness Formation Probability. Motivated by new developments in the asymptotics of Toeplitz determinants, we show how the crossover between the critical and o-critical behav...
